Details:

In matlab, inputs or outputs can be selectively ignored using the tilde ~
operator, Octave seem to think the use of ~ in these cases is a syntax error.

Example:

function [a, b] = example(a,b)
a = a +b;
b = a - b;
end

octave-3.2.4.exe:5> [a, ~] = example(1,2)
parse error:

  syntax error

>>> [a, ~] = example(1,2)
          ^
